The Department of Homeland Security, under Secretary Kristi Noem, announced on November 19, 2025, a determination to waive a broad array of federal laws to facilitate the swift construction of physical barriers and roads along the U.S.-Mexico border in Arizona. This move targets the Tucson Sector, identified as a hotspot for illegal entries and drug trafficking, with over 1.3 million apprehensions and significant drug seizures recorded since fiscal year 2021. The waiver, invoked under Section 102 of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), aims to achieve operational control of the border as mandated by Congress and reinforced by President Trump's Executive Order 14165. By suspending environmental, historical preservation, and other regulations, DHS seeks to address what it describes as an acute need for enhanced border infrastructure, highlighting the tension between security imperatives and regulatory protections.
Background and Legal Framework
Section 102 of IIRIRA empowers the DHS Secretary to install additional physical barriers and roads near the border to deter illegal crossings in high-entry areas. This authority was expanded through amendments, including the REAL ID Act of 2005 and the Secure Fence Act of 2006, which allow the Secretary to waive any legal requirements deemed necessary for expeditious construction. The current determination references these provisions, emphasizing Congress's definition of 'operational control' as preventing all unlawful entries, including those involving terrorists, narcotics, and contraband.
President Trump's Executive Order 14165, issued on January 20, 2025, directs DHS to deploy physical barriers to secure the southern border. This aligns with prior executive actions during Trump's previous administration, such as Executive Order 13767 in 2017, which similarly prioritized border wall construction. The Tucson Sector's designation stems from data showing 1,318,640 apprehensions from fiscal year 2021 through June 2025, alongside seizures of over 16,600 pounds of marijuana, 473 pounds of cocaine, 145 pounds of heroin, 8,224 pounds of methamphetamine, and 3,079 pounds of fentanyl. DHS asserts that these figures underscore the need for immediate action, building on historical patterns of migration and smuggling in the region.
Key Players and Project Details
Secretary Kristi Noem, appointed to lead DHS, exercises this waiver authority in her sole discretion, as granted by IIRIRA. The United States Border Patrol, part of DHS's Customs and Border Protection, provides the operational data justifying the project. The designated project areas include two segments: one starting at Border Monument 195 and extending east to Border Monument 163, and another from approximately 1.15 miles west of Border Monument 141 to Border Monument 70, both within Arizona's Tucson Sector.
Construction activities encompass not only barriers and roads but also supporting elements like lighting, cameras, sensors, drainage, and erosion controls. The waiver applies to a comprehensive list of statutes, including the National Environmental Policy Act (NEPA), which requires environmental impact assessments, the Endangered Species Act, protecting threatened wildlife, and the Clean Water Act, governing water pollution. Other waived laws cover historical preservation, such as the National Historic Preservation Act, and land management, like the Federal Land Policy and Management Act.
Relevant Precedents and Political Context
This waiver echoes previous invocations under Section 102. During the George W. Bush administration, similar waivers facilitated fence construction under the Secure Fence Act. The Trump administration expanded this in 2017 and beyond, waiving laws for projects in California, New Mexico, and Texas, often citing national security. Courts have generally upheld these waivers, as seen in cases like Center for Biological Diversity v. McAleenan (2019), where the Ninth Circuit affirmed the Secretary's broad discretion, though critics argued it undermined environmental protections.
Politically, the determination reflects ongoing debates over immigration policy. Proponents, including Republican lawmakers, view it as essential for border security amid rising encounters. Opponents, such as environmental groups and Democratic figures, contend it bypasses critical safeguards, potentially harming ecosystems and cultural sites. For instance, the project areas overlap with sensitive habitats, including parts of the Sonoran Desert, home to endangered species like the jaguar and Sonoran pronghorn. DHS maintains that since taking office, it has achieved the 'most secure border in history,' yet acknowledges the need for further measures.
Implications and Perspectives
In the short term, the waiver enables rapid construction, potentially reducing illegal crossings by enhancing detection and deterrence. DHS data suggests barriers have historically lowered apprehensions in fortified areas, though studies, such as a 2020 Government Accountability Office report, indicate mixed effectiveness, with smugglers adapting via tunnels or remote routes.
Long-term implications include environmental and legal ramifications. Waiving NEPA and the Endangered Species Act could lead to unmitigated impacts on biodiversity, prompting lawsuits from organizations like the Sierra Club, which have challenged prior waivers. Economically, construction may boost local jobs in Arizona but strain federal budgets, with costs for similar projects exceeding $20 million per mile in the past.
Different perspectives highlight divisions: border security advocates praise the move as fulfilling congressional mandates, while civil liberties groups, such as the American Civil Liberties Union, argue it erodes checks and balances. Indigenous communities, affected by waivers of the Native American Graves Protection and Repatriation Act, express concerns over sacred sites. DHS counters that the action is narrowly tailored to high-risk areas, preserving prior waivers and reserving authority for future needs.
The determination sets the stage for ongoing border security efforts, with potential expansions if migration pressures persist. Challenges include judicial reviews, though precedents favor DHS discretion, and congressional oversight, where funding debates could arise. Debates will likely continue on balancing security with environmental and humanitarian considerations, influencing future policy trajectories.
